'A vfollower plate 22 in thel form of bowed metal: strip vprovided with'a raised centrally located cam surface 23. is mounted against the outer clamping' plate "off each groupin ,such wise that the saidcain vsurr kfaces 23 incline' downwardly and inwardly,

The retaining plate 20 is provided with ears 26 having screw threaded openings therein which ears when said plate is in position project into correspondingly shaped recesses 27 in the disk like member 11 with the screw threaded apertures thereof in alinement with apertures 28 provided in the disk like member 11, and also with apertures 13 in the yend walls 14 of bearing member 12, all shown more clearly in 2,

Headed screw threaded members29 having smooth inner ends 30 screw threadedly engage ears 26 of -the..retaining`plate 20j' in such wise that the inner ends thereof engage apertures 1-3 of bearing'member 12 serving as trunnions therefor. Nhen in this position the heads of said members 29 lie entirely within apertures i 28 vin disk like member 15. In this manner, the members c 15 and 2() are secured operatively together,

adjusting screws 25 serving to hold the parts irmlyvand against relative vibration or rattling in addition to providing the clamping action on the bearing member 12. Retaining plate 2O is also provided with a central opening of rectangular design corresponding to opening 16 in member 15 for receiving the is obstructed soV that the entire support is effectively locked against removal except from the interior of the vehicle where the same may be removed by, first removing clamping ring 31. RemovalV from theexterior of ,the vehicle, however,v is not feasible.

The bearing member, 12 its outer end terminates in an outwardly flared member 32 which is provided with diametrically opposite outwardly extending arms or fingers 33,-each apertured, as at 34. The lamp'is shown at 35, and comprises the usual reliector 36, glass front 37 and crimped retaining ring 38. At its reduced portion 39,'reflector 36 is attached to socket portion 40 which lat;

ter projects rearwardly between the arms 33 of the bearing member, 12, whichare carried ,i at the outerendj of stem .Thesocket poi#` tion 4 0 of the lamp provided with diametrichly..opposite,emailadresse.Perinatal ber. uscrews 25 and nuts 44 the spot light willrbe which receive and retain the headed ends 42 of screw threaded trunnions 43, the latter projecting outwardly in opposite directions through the apertures of said raised portions and through the apertures 34 in arms 3 3, suitable nuts or the like 44 engaging the trunnions at ltheir outer ends and holding the lamp in position. The openings in the raised portions 41 through which the trunnions extend are of irregular contour and the said trunnions correspondingly shaped so that relative rotative movement is prevented. Intermediate one of the raised portions 41 and the adjacent arm 33 a gear se'gment is interposed through which the correspondin'g trunnion 43 also extends. The opening in the gear segment through which the` trunnion extends is also of irregular contour corresponding to that of the trunnion so that relative rotation is prevented,

or, inother words, sothat upon movement Y of the gear segment the lamp will be angularly adjusted in either one direction or the otherl Y Y I .f

Extending through and journaled in the hollow stem 10 is an operating rod 55 provided at its inner end with Va knob 56 and which at its outer end is slightly reduced, as at 57 and has Vfixed thereon a gear wheel 58. This gear wheel 58 meshes with segment gear 45 so thatany rotational adjustments of rod 55 will result in lamp 35 being adjusted in one direction or the other on its supporting trunnions, as will be readily understood. It is referred to construct the so that the lampmay have a corresponding range of adjustment in the horizontal plane.

`In addition to adjustments in the horizontal Athe vertical Mplane regardless of the hori* zontal adjustment thereof, `and if desired the lamp may be adjusted in both planes si- .multaneously in that both adjustments4 arc effected through a common operating mem- Through proper adjustment of the maintained in any of its various positions of. adjustment without danger ofaccidental `displacementdue to vibration, or the'V like.

" The trunnion 43 which carries lthe gear segment 45V may be hollow to permit ofqthe wiring cord 46 being projected ,therethrough into the base 47 of the socket Ifor connection totheterminals in the usual manner. From the hollow trunnionV 43 this cord is Apreferl ably extended directly through `suitable openings 48 in the cylindrical bearing inember 12 and into thev interior Ofthevehicle .where a switch of-any `suitable .Hype may be interposed, and, @Onveiiently meunted .n-the segment gear 45 o substantially`180 extent A front compartment of ,they vehicle Within easy reach of the driver.

The incandescent lamp is shown at 49 and f is removably held in the socket by means of the usual bayonet joint. The sleeve 50 in which the bayonet slots are formed is longitudinally adjustable to permit of proper focusing of the lamp. This adjustment of sleeve may be quickly effected through the instruinentalities of the flat headed sore-w 51 and nut 52 from the exterior of the lamp casing and Without dismantling the lamp or any of the other parts of the spot light. The square head of screw 51 is' receivedl Within a similarly shaped opening 53' in the sleeve v50, the shank projecting outwardly through slot 54 in the socket portion 40 of the casing,

the slot being of such size as to prevent the Vhead passing therethrough. Thus, it will be observed that by loosening nut 52 the same may be employed to move sleeve back or forth to properly focus the lamp. When the desired or proper positionv has been reached the nut 52 is again tightenedv to hold the parts in adjusted position.

It will be obvious to those skilled in the;y

art that the invention is susceptible of various changes and modifications Without-departing from the spirit thereof, and accordingly it is not desired to limit or restrict the same to the particular form or arrangementof parts herein illustrated and describedv except where limitations1 appear in the appended claims.

I claim l. In combination with a vehicle windshield or the like, a spotlight comprising a lamp casing infront of the windshield, a

support for said casing extending' through an opening in the windshield and pivotally jointed at a point in front'of the latter, mounting means secured in the windshield opening and pivotally carrying the support at an axis substantially inthe plane of the yglass and transverse to the axis of theP -pivotal joint.

2. `In vcombination withv a vehicle Windshield or the like, a spotlight comprising a lamp casing positioned in front of the Windshield, a support for said casing extending' through an opening in the WindshieldV and pivotally jointed at a vertical axis between the lamp and the windshield, mountingv means secured in the windshield openiingyfr and pivotally carrying the support at'a horizontal axis substantially in the plane of the glass. A

3. In the combination definedin claim l,

means carried bythe support atfthe rear side of the windshield relatively movable in said support and operatively connected with the lamp casingfor swinging it about the Y axis transverse to that of the enlargement,

together with a shaft j ournaled in the hollow stem, gearing connecting the forward'end of said shaft with the lamp casing for swingingv it about the axis of the said joint and a handleV for said shaft at the rear side ofthe Windshield adapted for rotating the yshaft or rocking the stemY at will.

In testimony whereof, I have hereunto set my hand at Chicago, Illinois, this 12th day of March, 1924.l
